Instructions

Line your pan: Grease and line an 8x4 or 9x5-inch loaf pan with parchment paper, leaving overhang on the sides for easy removal.
Add dry ingredients: Mix in the chocolate protein powder, cocoa powder, pumpkin seed powder, and ground chia seeds. Pulse a few times to combine the ingredients (Or stir to combine).
¾ cup chocolate protein powder, 3 tablespoons cocoa powder, ¼ cup pumpkin seed powder, 2 tablespoons ground chia seeds
Add wet ingredients: Add the maple syrup, peanut butter, and vanilla extract. The mixture will be thick and dough-like. Add half of the milk, then pulse and wipe down the sides of the bowl. Then repeat with the remaining milk and pulse until it holds together when pressed (like cookie dough). It should not be overly wet or sticky.
2 tablespoons maple syrup, ⅔ cup peanut butter, 1 teaspoon vanilla extract, 8 tablespoons almond milk
Press into pan: Transfer the mixture to your lined pan. Press firmly and evenly with your hands or the bottom of a glass to create a smooth, compact layer.
Add topping (optional but recommended): Melt the chocolate chips with coconut oil in the microwave (20-second bursts, stirring in between) or over a double boiler. Pour over the bars and spread evenly. Sprinkle with topings like: cacao nibs, chocolate chips, flaky salt, or colorful mini candies (for a cosmic brownie vibe) while the chocoalte is still wet.
¼ cup semi-sweet chocolate chips, 1 teaspoon coconut oil
Chill: Refrigerate for at least 30–60 minutes (or freeze for 10–15 minutes) until firm. Once set, lift out using the parchment and cut into 10 bars.
Store: Keep in an airtight container in the fridge for up to 1 week, or freeze for up to 2 months (thaw in the fridge or at room temp for a few minutes).

Notes

Pumpkin Seed Protein Powder

I prefer using pumpkin seed protein powder. It is a specialty product, but it's so worth it because it helps create a creamy texture and nutty flavor. And it adds magnesium, potassium, and even a little bit of zinc to these yummy bars.

You can substitute oat flour or almond flour.

Pro Tip for Slicing: For those perfectly clean 'professional' edges, wipe your knife with a warm, damp cloth between every single cut. It keeps the chocolate topping from cracking and the fudgy center from sticking!

Tips for Success & Variations

Protein powder matters — Chocolate-flavored works best. Avoid super-sweet or artificial-tasting ones. Whey tends to give a smoother texture; plant-based keeps it vegan.
Too dry? Add a splash more milk or syrup. Too sticky? Add a bit more protein powder.
Flavor boosts: Add ½ tsp espresso powder for mocha brownie bars, or a pinch of cinnamon.
Chocolate Boost: Add 2 tablespoons of mini semi-sweet chocolate chips to the batter.
